Target board : AM335x Starter Kti

SDK : ti-sdk-am335x-evm-05.05.01.00

u-boot make command : make O=am335x CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm am335x_evm_spiboot

SPI flash : mx25l25635e , connect to Starter Kit J11

My process :

1. boot from SD card

2. into u-boot ( u-boot can probe the SPI0 and found SPI flash device)

3. get image file from tftpboot : MLO.spi , u-boot.img and use sf write image in to SPI flash (sf erase SPI flash first)

Now , i power off the target board , remove SD Card , power on the target board .

But not see any debug message from console port.

I think starter kit boot mode first is MMC , but i can't found any information about this kit boot mode setting.

How can i change the starter kit boot mode setting and where can found this information ?

Hi Lucas,

There is a group of pullup/pulldown resistors for boot mode setting. You can see them at the bottom of page 6 of the Starter Kit schematics.

Thanks , i see.

Starter Kit is setting in (10111) MMC0 , SPI0, UART0, USB0

That mean , if my SPI flash is burn correct image (MLO.spi and u-boot.bin) , when remove the SD card and power on the kit .

It sure be boot from SPI Flash , right ?

That's correct. I think it has been discussed on this forum and people have done it. You could try to search threads that are related to yours with the "Search Community" window on top-right of the screen.
